Removal Procedure

WARNING: This page is about a different variant/trim than selected.
WARNING:

Avoid unnecessary contact between the fuel feed intermediate pipes and any other parts. This could cause damage to the mating joints. Damage to the mating joints may cause a fuel leak. A fuel leak could cause an engine fire resulting in catastrophic engine and vehicle damage, and possible injury or death.

CAUTION:

Fuel feed intermediate pipes will be delivered with shipping caps that are meant to protect the mating joint threads. Do NOT remove shipping caps until the pipe is to be installed and joints are to be secured. Failure to do so could result in damage to the mating threads.

NOTE:
  • Do NOT reuse the fuel feed intermediate pipe. If the fuel feed intermediate pipe fittings are loosened or the pipes are removed, the pipes MUST be replaced.
  • The tightening order and torque are CRITICAL to proper fuel system fit and function. Be sure to follow installation and tightening steps EXACTLY.
